Answer:
s₁ = 2 m/s
Step-by-step explanation:
given,
distance between Melissa and friend = 3 mile
walking speed = s₁
bike speed = s₂
total time of the trip = 2 hour
given,
s₂ = s₁ + 4
2(s₁ +4)s₁ = 3 (s₁ + s₁ + 4)
2 s₁² + 8 s₁ = 6 s₁ + 12
s₁² + s₁ - 6 = 0
s₁² + 3 s₁ - 2 s₁ - 6 = 0
(s₁ + 3) (s₁ -2) = 0
s₁ = -3 , 2
s₁ = 2 m/s
walking speed of the Melissa is s₁ = 2 m/s

Step-by-step explanation:
Answer:
x=24
<6=79°
Step-by-step explanation:
We can see that if we add 3x+7 and 4x+5, it will total a 180-degree angle. This allows us to solve for x. 3x+7+4x+5=180 7x+12=180 7x=180-12 7x=168 x=24 We can also see that angle six is the same as the angle 3x+7. Since we know x=24, we can solve for those angles. 3(24)+7= 72+7=79 So <6=79 degrees
The formula of the present value of an annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 280000
PMT monthly payment?
R interest rate 0.06
K compounded monthly 12
N time 20 years
Solve the formula for PMT
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
PMT=280,000÷((1−(1+0.06÷12)^(
−12×20))÷(0.06÷12))
=2,006.01
